Threading Tap FANAR NPT 1" -11.1/2 DIN-24230 HSS 800 (N1-121001-4639)

FANAR threading tap NPT 1" -11.1/2 manufactured to DIN‑24230 in HSS 800 tool steel is designed for cutting and repairing tapered NPT pipe threads in metalworking and plumbing applications. The tool matches DIN‑24230 geometry for tapered NPT threads and is suitable for use in both hand and machine tapping setups where high wear resistance and dimensional accuracy are required. Made from HSS 800, the tap offers a balance of toughness and hardness for repeated thread cutting in common construction and industrial materials.

Advantages

The FANAR NPT 1" -11.1/2 tap provides consistent thread form according to DIN‑24230 and reliable dimensional conformity for tapered pipe connections. The HSS 800 material increases tool life and resistance to abrasion compared with standard high‑speed steels, while the precise cutting geometry reduces required torque and improves chip evacuation. The tap is suitable for both repair and production tasks and can be used in manual or powered tapping equipment when DIN‑24230 compatibility is needed.

Suitable for

• Cutting new tapered NPT 1" -11.1/2 pipe threads in steel and non‑ferrous metals
• Repairing damaged or worn NPT tapered threads on fittings and pipes
• Use in production lines and maintenance workshops with hand or machine tapping setups
• Applications requiring DIN‑24230 dimensional conformity for NPT threads

Key specifications

• Thread form: tapered NPT 1" -11.1/2
• Standard: DIN‑24230 thread geometry
• Material: HSS 800 tool steel
• Intended use: cutting and repairing NPT tapered pipe threads
• Compatibility: suitable for hand tapping and machine tapping operations

How to use

Select appropriate machining lubricant and secure the workpiece before starting. For hand tapping, use a compatible tap wrench and apply steady, even pressure while rotating the tap, backing off periodically to break and clear chips. For machine tapping, set correct speeds and feeds for the material being machined and use suitable tapping holders or adapters to ensure axial alignment. Ensure the tap is driven true to the axis of the hole to maintain DIN‑24230 thread accuracy and avoid premature tool wear or thread damage.

Usage recommendations

Use cutting fluid appropriate for the workpiece material to extend tool life and improve surface finish. Inspect the tap regularly for wear or chipping and replace if thread form degrades. For damaged threads, start with a cleaning pass and use incremental engagement depths rather than forcing full depth in a single pass. When used in machines, verify alignment and clamping to prevent breakage.
